Solution
The correct option is D If both the assertion and reason are false Interferons refer to a group of soluble glycoproteins that are produced and released from cells in response to virus infection (and other stimuli). So, the assertion is false beacause Interferons are produced by viral cells. Interferons are not released in the time of injury, inflammation of injury is caused for the blockage due to fibrinogen and the irritation is caused for WBC exposing. So, the reason is also false. So, the correct option is option D
